Traceroute --help

`traceroute` 是一个用于网络故障排除和网络性能分析的命令行工具。 它可以显示从本地计算机到目标计算机的路径，以及每个节点的延迟和丢包情况。

以下是 `traceroute` 命令的帮助信息：

Usage: traceroute [-nrv] [-m <max_ttl>] [-p <port>] [-q <nqueries>] [-s <src_addr>] [-t <tos>] [-w <wait>] <host>

Options:
  -m <max_ttl>  Set the maximum number of hops to <max_ttl> (default: 30)
  -p <port>     Set the destination port to <port> (default: 33434)
  -q <nqueries> Set the number of probes per hop to <nqueries> (default: 3)
  -s <src_addr> Set the source address to <src_addr> (default: the primary IP address of the local host)
  -t <tos>      Set the IP type of service to <tos> (default: 0)
  -w <wait>     Set the time to wait for a response to each probe to <wait> seconds (default: 5)
  -n            Do not resolve hostnames to IP addresses
  -r            Bypass the normal routing tables and send directly to each hop
  -v            Verbose output (include IP addresses and port numbers)

可以使用 `traceroute` 命令加上对应的选项和目标主机名或 IP 地址来使用该命令。例如，`traceroute www.google.com` 将显示到 Google 服务器的路径。
